4 Overview - How the tutorial is organized This tutorial is broken into two sections: 1) un the Vacuum Line - This section describes how to connect the vacuum tee at the intake manifold, and how to route the plastic vacuum line from the tee to the vacuum transducer inside the cabin. 2) Install the Vent Pod and Gauge - This section shows how to disassemble the dashboard vents, install the vent pod and vacuum/boost gauge, and splice the wiring. Section 1 - un the vacuum line to the transducer In this section we will connect the vacuum/boost sensing line to a vacuum source at the intake manifold, and then run the line through the firewall, into the cabin area beneath the dash. Use the schematic below to identify major component locations and hose routing. The photos on the following pages show how to: boost sensing transducer Insert the vacuum tee in the vacuum line at the intake manifold. Connect the tee to the long length of plastic line using a short length of braided vacuum hose. oute the plastic vacuum line from the engine compartment to the grommet in the firewall. oute the plastic vacuum line through the firewall grommet into the cabin, below the dashboard. Connect the moisture filter and vacuum/boost pressure transducer to the plastic vacuum line, using short lengths of braided vacuum hose. computer box hood release cable grommet wire harness to boost gauge moisture filter The vacuum tee, plastic line, clamps, and braided rubber hose are all included in your kit. Use the zip ties to secure all lines and hoses safely away from moving components, like pedals and the steering mechanism. Page - 4

5 Section 1 - un the Vacuum Line - Install the Transducer Step 1 - Under the hood- Install the vacuum tee. Open the hood. Locate the vacuum line located at the left rear of the intake manifold. (For reference, the hose is close to the coolant recovery bottle.) Cut the hose, as shown. Step 2 - Under the hood- Install the vacuum tee. Slide one crimp clamp over each length of hose and insert the vacuum tee between the hoses. When the tee is properly positioned, use the end nippers to crimp the clamps tight. (We prefer placing the small vacuum nipple in the tee at 12 o clock to allow any moisture in the hose to drain back to the manifold, making it less apt to freeze in cold weather.) Step 3 - Under the hood- emove the rain tray Pull the rubber weatherstrip from the front of the plastic rain tray cover. Then pull the rain tray up slightly and straight forward to remove it.

6 Section 1 - un the Vacuum Line - Install the Transducer Step 4 - Under the hood- oute the plastic line Attach a short length of braided rubber hose to the vacuum tee nipple (tight fit, so push hard!). un the semi-rigid plastic vacuum line from the braided hose, across the front of the water tray to the rubber grommet located to the right of the battery. Push the line through the grommet. Then route the line back across the tray, in front of the battery, to the rubber firewall grommet located next to the brake booster. Use the zip ties in the kit to secure the plastic line at several locations. Leave a slight bend in the rubber braided hose at the vacuum tee to compensate for engine movement and vibration. Step 5 - Under the hood- Punch a hole in the firewall grommet Punch a small hole in the rubber grommet in the firewall (arrow), located between the brake vacuum booster and ECM. Page - 6

7 Section 1 - un the Vacuum Line - Install the Transducer Step 6 - Under the hood- Push line through grommet Push the plastic vacuum line through the small hole in the rubber grommet, into the cabin. Now it s time to move inside the cabin. Step 7 - Under the dash - emove fuse panel cover emove the underdash panel. Open the driver side door and pry off the fuse panel cover to expose the side dash panel attachment bolt (arrow). Use an 8mm socket and ratchet to remove the bolt. Step 8 - Under the dash - Drop underdash panel emove the two additional bolts from the underdash panel using the same 8mm socket and ratchet. Drop the panel down and unclip the purple data link connector and footwell lamp. No need to unplug them; just unclip both from the underdash panel and let them hang. Page - 7

The schematic below shows all component locations inside the car, and identifies the wire connections. brown light switch Vent Pod Vacuum Boost Gauge Wiring Connections and Component Locations Audi B6 A4 gauge power harness transducer harness black red gray/blue use alternate wiring for cars with auto headlight switch - see photos below black transducer red green white gauge power harness standard headlight switch electrical connector Special Note for Cars equipped with Auto Headlight Switch If your car has an Auto Headlight Switch, there is no keyed hot terminal (black wire) at the headlight harness connector. You ll need to pick up keyed voltage at the fuse box. To do so, install the fuse tap in your kit on the 15 amp fuse indicated in our photo. Attach the fuse tap to the fuse as shown and reinsert the fuse. Connect the red wire from the gauge harness to the fuse tap using the insulated terminal in the kit. Page - 9

10 Section 2 - Install and Connect Vacuum/Boost Gauge Step 1 - emove the dash vents Using a non-marring trim removal tool, pry the center vent assembly from the dash. Work your way around the perimeter to compress the spring clips as you pull the vent straight out. Step 2 - emove the vertical vents Pull the vent from the dash; flip it over and unplug the electrical connector. Step 3 - emove the Vent Cover Use a small common screwdriver to pry the tabs on the vent cover. Pry them loose one at a time until the cover pops off. Page - 10

11 Section 2 - Install and Connect Vacuum/Boost Gauge Step 4 - emove the louvers Pull the horizontal and vertical vent louvers from the left hand vent housing. Step 5 - Cut a notch in the vent flap Turn the assembly over. Use your X-ACTO knife to cut a square notch in the air control vent flap in the area highlighted in the photo. Step 6 - Drill a hole in the vent body Flip the vent housing over; drill a ½-inch hole in the location shown. Page - 11

12 Section 2 - Install and Connect Vacuum/Boost Gauge Step 7 - Pull the cables to the vent opening in the dash oute the gauge power cable and the transducer cable up through the left underdash area to the vent opening in the dash. Step 8 - Plug in the gauge Hold the vent housing up close to the vent opening and feed the two cables through the ½-inch hole drilled earlier. Pull both cables through the vent housing opening (arrows). Step 9 - Install the vent pod Hold the vent pod up to the opening. Feed the two cables through the round gauge hole, and let them hang.
